All you need:
-2 Bottles
- These bottles can be any size as long as they are the same.
- Use water bottles, milk cartons, and juice bottles, anything
you can find!
- Obviously, the larger the bottle the more it can hold therefore
different sizes will mean different weights, making it heavier
and harder or lighter and easier.
-Something to fill the bottles with.
- Be creative! Different materials will also mean different
weights.
So, if you want it heavier, use rocks for example, or if you
want the weight lighter, use rice or pasta.
- Examples of fillers: Water, sand, dirt, rice, pasta, rocks, can
you think of any more?
